ADVERTISING DEVICE FOR WEIGHING-SCALES.

Specification of Letters Patent.

Patented July 20, 1920.

Application filed February 28, 1920. Serial No. 362,081.

To aZZ whom it may concern:

Be it known that I, VViLLIAM J. VANDER- can, of Cohoes, in the county ofAlbany, in the State of New York, have invented new and usefulImprovements in Advertising Devices for lVeighing-Scales, of which thefollowing, taken in connection with the accompanying drawings, is afull, clear, and exact description.

This invention relates to certain improvements in advertisingattachments for weighing scales, in which a suitable dial is mountedupon the upper end of an upright stainlard carried by a laterallyprojecting base upon which is mounted a platform which is mounted in anywell known manner so as to have a slight vertical movement relatively tothe base.

Suitable mechanism is also provided for transmitting motion from themovable platform to a rotary pointer which is movable around the dial,the latter being inclosed in a case for protection against injury.

The means for transmitting motion from the movable platform to theindicator or platform involves, in this instance, the use of a verticalreciprocatory frame within the dial case and connected to a mainsupporting frame by retracting springs for returning the movable partsto their normal positions with the pointer at the zero graduation of thedial.

The main object of my present invention is to provide the upper portionof the dial case with a supplemental case having a lengthwise opening inthe front side thereof and adapted to contain a multi-sided rotary drumhaving advertising matter on each side and to provide suitable meansoperated by the vertical movable frame for rotating said drum step bystep at each depression of the movable platform for successivelypresenting the sides of the drum containing the advertising matter tothe opening in the front of the supplemental case, where it is easilyvisible to the operator of the platform. Another object is to providemeans for preventing the rotation of the drum in a reverse direction andfor holding it in its adjusted position. A further object is to providea supplemental drum with a movable end wall to permit the drum to beremoved and replaced when necessary to change the advertising matterthereon or for any other cause.

In the drawings:

Figure -1 is a front elevation of the upper portion of a weighing scalesshowing my mproved. advertising device thereon. Fig. 2 is a sectionalview through the interior of the dial case and supplemental case andupper portion of the standard showing the vertical moving frame as retracting means, and also showing the connections between said frame andthe advertising drum for rotating the latter step by step.

Fig. is an end View of the supplemental case and drum and adjacentportion of the dial case, the movable end wall being open.

Fig. is a transverse vertical sectional view taken on line 4-4, Fig. 1.

In order that my invention may be clearly understood. I have shown theupper portion of an upright column or standard 1- carrying at its upperend a dial case 2- which is adapted to receive and support asupplemental advertising case 3 above the dial, as

The column -1-- is, made of any desired height to permit the dial to bereadily visible to the user when standing upon the platform. the lowerend of the column being secured to any well known form of baseprojecting forwardly therefrom and carrying the usual platform which hasa slight vertical movement and is mounted upon the usual supportinglevers common in weighing scales of this character.

An indicator or pointer -5 is pivoted at -6 coaxial with the dial 4 tomove around the graduations thereon. a main supporting frame -T- issecured to and within the dial case 2 and is provided near its upper endwith forwardly projecting lugs -S in laterally spaced relation forreceiving a pair of adjustable anchor bolts -9 having pendent members-10- pivoted thereto; a pair of springs ll are at tached at their upperends to the members --10- and have their lower ends attached to theopposite arms of a Ushaped frame 12- which is moval'ile vertically andis adapted to be actuated by suitable connections between said verticalmovable frame and the platform of the scales, said connectionsincluding, in this instance, a vertical movable rod tilwhich isconnected to the lower rrosbar of the U-shaped frame -li3- and operatesto draw said frame dowinvardly against the action of the retractingsprings -llwhen pressure is applied to the movable platform not shown.

The vertical movement of the frame -1Q is utilized to operate a rotaryadvertising drum llthrough the medium of a push-rod -15 having its lowerend attached to a laterally projecting arm 16 on the frame l2 and itsupper end provided with a pawl il for engagement with the teeth of agear wheel 18- which meshes with a similar gear -lS' on one end of thedrum 1a-.

This drum is mounted upon a central shaft or spindle l9- which isjournaled at its ends in suitable hearings -2[)- in the end walls of thesupplemental case --3 at right angles to the plane of movement of theframe l2, said. drum being angular or multi-sided in cross-sections, inthis in stance, octagonal, and wholly within the supplemental case 3. lprefer, however, to support the end of the drum nearest the movable endwall upon a supplemental bean ing 2ll'- which is rcmovably secured toand within the case -8 and upon which the gear or ratchet wheel 18- isjournaled, thus permitting the end wall -El'- to be opened for theremoval and replacement of the aiilvertising cards without disturbingthe. drum.

The major portion of the case -----3 "is preferably circular incross-section and is provided with an opening -2.1- in its front side,corresponding approximately in width and length to the length and widthof one side of the drum 1 l-, one end of the case being fixed, while theother end, ;lis preferably hinged at i;-2 to permit it to be opened andclosed for the removal and replacement of the drum -l4 when desired. Thepawl 1 7 is pivoted to the upper end of the push-rod -l5- which isguided in a vertical opening 23- in one side of the dial case -52, saidpawl being free to ride over the teeth of the gear against the action ofa light retracting spring -li" as the rod 3 1") is drawn downwardly andto engage said teeth to rotate the drum one tooth space at each upwardmovement of the frame l2 by the springs -llto avoid extra load upon theweighing scales.

The number of teeth in the ratchet wheel 18 preferably correspond to thenum ber of sides of the drum --l4 and are proportionate as to length tocorrespond to the movement of the frame l2 so that at each upwardmovement of said frame, the

pawl -l7 will rotate the drum one tooth space to successively registerits several sides with the opening 2l-, czu'li side of the drum beingprovided with such advertising matter as it may be desired to displaythrough said opening.

A detent 24: is pivoted at one end to a lug -25 on the case 3- and hasits other end adapted to engage the teeth of the ratchet wheel -18 toprevent reverse movement of the drum after each operation by the pawl--17-.

The supplemental case -3-- is preferably made separate from the dialcase -2-, but is secured thereto by screws -26 when their parts areassembled for use, the opening in the front side of the case --3- beingclosed by a glass or other transparent plate -27 to permit theadvertising matter on the registering side of the drum to be easily readtherethrough by the operator standing upon the platform of the scales.

Each side of the drum -14 is provided with opposite grooves or ways -27-into which the card or other member bearing advertising matter may bereadily inserted and which serve to retain said card or plate inoperative position, while, at the same time, permitting its ondwiseremoval and replacement by other cards when necessary or desirable.

It has not been deemed necessary to show the platform and mechanism fortransmitting motion therefrom to the draw-rod --i for the reason thatsuch mechanism is well understood by those skilled in the art, and, in.like manner, any suitable mechanism may be employed for transmittingmotion from the movable frame -12- to the pointer 5 because suchmechanism does not form a part of my present invention.

What I claim is:

1. In. a weighing scale of the character described, the combination of adial case, a supplemental case mounted upon the top of the dial case andprovided with an opening in one side, and also having a movable end wallto permit access to the interior thereof, a vertical reciprocatory framewithin the dial case, a drum rotatably mounted within the supplementalease and movable across said opening, a ratchet wheel on one end of thedrum, a pawl engaged with the ratchet wheel and a rod connecting themovable frame with said pawl to cause the rotation of the drum step bystep one tooth space at a time at each successive movement of the framein one direction.

In a weighing scale of the character described, the combination of adial case, a.

dial in the front side thereof, a vertical reciprocatory frame movablewithin the dial. case, a supplemental case secured to the top of thedial case and provided with an opening in its front side, a multi-sidedequilateral drum rotatably mounted within the supplemental ease andhaving its sides movable across and in close proximity to the openingtherein, means actuated by successive movements of said frame in onedirection for rotating the drum step by step to successively present theseveral sides to said opening, and means for preventing a reversemovement of the drum.

In witness whereof I have hereunto set my hand this 17th day ofDecember, 1915).
